Physics Question: Two bicyclists , starting at the same place , are riding toward the same campground by two different routes. One cyclist rides 1080 m due east and then turns due north and travels another 1430 m before reaching the campground. The second cyclist starts out by heading due north for 1950 m and then turns and heads directly toward the campground. (a) At the turning point , how far is the second cyclist from the campground ? (b) In what direction (measured relative to due east) must the second cyclist head during the last part of the trip ?

A bike has a displacement of 1.27 km after a trip consisting of three segments x1, x2, and x3 along a straight line. The sum of the first two segments is 3.79 km, the sum of the last two segments is -7.82 km. How long is each segment?
